Before Google's $35 Chromecast, the Roku LT was the original impossibly priced streamer that seemed too good to be true, offering up tons of streaming content in a tiny box for just $50. At $29.99, it's a steal, and you should be locked up. No, seriously. Call the constabulary.
Sure, with only 4GB of hard drive space, it's not exactly the best option for gamers, but at only $99 it's a great option for streaming media. The console is compatible with Xbox Slim hard drives which means you can upgrade the storage fairly easily.
Just because you're going for a sound bar doesn't mean you can't have real surround sound. The Vizio S4251W-B4 is one of the few "true" surround sound bars, and at $198 it's almost a no-brainer. Get it at that price on Friday at Walmart -- or right now at Amazon.
